questions on TTML specification

Hi,

I have some questions to TTML specificaton.
I appriciate if you reply my questions.
Forgive me if there were same questions in archive...

(a) What is expected if tts:backgroundColor is applied to body element?

(b) What is correct understanding of PRUNE (E) (defined in 9.3.2)
  ==> 
    prune the element and its descendant elements
  or
    prune the element and set its parent element as parent element of
     its child elements

(c) region reference
  what is expected in following example?

  <definitions of regions>
   <body>
     <div>
       <p> 
         oh
         <span region="r1">
            my
         <span region="r2">
            god
          </span>
          </span>
       </p>
      </div>
    </body>
 ==> which region(s) "oh" will be appeared?
    both r1 and r2? or will "oh" not be appeared?

(d) region style prop inheritance
  what is expected in following example?
    <definition of r1 and r2 (no tts:color definitions in both)...>
    <body>
     <div region="r1" tts:color="red">
       <p begin="1s" end="2s"> 
         text1
       </p>
       <p region="r2" begin="1s" end="2s">
         text2
      </div>
    </body>
  ==> what is the color of "text2"?

Uchimura
